4. Pre-4.0 Development Versions

This section is included mostly for historical reasons.

The development leading up to 4.0 started from version 3.2A, but much of
it happened on a separate development branch. The "new design" work on
that development branch was first folded into the main development branch
at version 3.9N. Up until the XFree86 CVS was made publicly available,
all versions containing one or more letters were internal development
snapshots. The internal development snapshots continued through the
following sequence: 3.9N, 3.9Na, ..., 3.9Nz, 3.9P, 3.9Pa, ..., 3.9Py,
3.9.15, 3.9.15a, ..., 3.9.16, 3.9.16a, ..., 3.9.17, 3.9.17a, ..., 3.9.18,
3.9.18a, ..., 4.0. The 3.9.15, 3.9.16, etc versions were public pre-4.0
beta releases.
